Routing problem - from PSTN via Meridian to TIE - PBX Info :: Your Free PBX, PABX and Telephone Information Resource

Hello all,

I have got a problem that maybe easy for someone of you, so maybe you could help.
I configured 4 members route using 2 ISDN ports on SILC card. To this route I connected Cisco Voice router with CallManager. Everything works fine until incoming call is internal. Using ACOD all works fine. CDP makes calls easier.
Seems IP phones should be reachable from PSTN also. The true is Caller receives busy tone (network busy).
I tried many configurations of route but without result. Maybe I looks for in wrong places.

Please help.
Mr.D

Your callers receive a busy tone from the PSTN meridian pbx to the Cisco IP phone? Does it happen the other way around?

Callers gets busy tone when they call externaly to Meridian DN range (CDP) that should be routed to LAN-PBX via TIE.
Internal calls are routed without any problem.

this might help, I had a simular problem on a E1 pstn to E1 cicso router, using a DSC, at the end of the day it was the default DMI table that seem to have been the problem. I created a DMI table with nothing much in it (INS 0, del 0) and the problem disappeared.

What I use with CDP(DSC) is below:

DMI 49
DEL 0
CTYP NCHG

so it is not a problem

but thanks

Mr.D
